My cat has been suffering with skin patches that end up in

Hi my cat has been suffering with skin patches that end up in sores and they only seem to appear on the bottom half of his body.He is an outdoor cat. One patch is on the armpit,one on his front leg elbow,one next to his nipple.We have taken him to the vet but she cant figure out what it is and he has been given some steroid tablets which help for a bit but then they re appear on the same place.He is eating fine and we feed him good food wet and dry.He keeps licking the sores all the time.Could it be a dermatitis issue?They are slightly raised dry patches about 3cm big and when licked and sore they weep a little and bleed too.

Dermatitis means inflammation of the skin which is present but doesn't tell us the cause of the inflammation.

sure here you are

Thank you. Give me a moment to take a look, please...

The photo reveals an unusual epidermal collarette (roughly circular skin lesion) on feline skin. My two main differentials are an unusual dermatophyte (ringworm fungus) such as Trichophyton or epitheliotropic lymphoma and the eosinophilic dermatitis complex should always be a consideration as it can appear in many forms. I would fungal culture hairs from the periphery of lesions and if negative take a few skin biopsies and let my pathologist make the diagnosis for me. Please continue our conversation if you wish.

He is still on tablets for it and they are Prednidale Tabs 5mg so should we still wait until the course is finished?

The prednisolone can be very effective when addressing eosinophilic dermatitis, would temporarily improve the appearance of lymphoma but would worsen a fungal infection. You mentioned that the prednisolone helped for a bit but the skin lesions reappeared and so I would expect the same to occur this time around. There's no significant harm from finishing the prescription but if you didn't see complete resolution of the skin disorder after doing so, testing as I recommended should be considered.

Ok thank you so much for your help.i will have to take him back to our vet to do the sample once the course is finished.
